Abstract

L'invention concerne des affaiblisseurs de fibres optiques et des systèmes d'affaiblissement (100) qui permettent d'extraire sous contrôle l'énergie optique d'une fibre optique (30), et donc d'affaiblir le signal optique transmis via ladite fibre (30). Selon un aspect, on enlève du matériau sur une partie de fibre (30), de manière à exposer un surface d'extraction de l'énergie optique. Un matériau contrôlable est constitué sur ladite surface, de manière à permettre l'extraction sous contrôle de l'énergie optique selon un stimulus modifiable appliqué à la surface en question, stimulus qui affecte l'indice de réfraction. Selon une variante améliorée, un matériau contrôlable est constitué sur la surface exposée, de manière à contrôler quantitativement l'extraction d'énergie optique dans la fibre optique, et un matériau en vrac est constitué sur le matériau contrôlable, aux fins de rayonnement de l'énergie optique extraite.
